The LM3S2919-IQC50-A2: The 100-LQFP package (14x14 mm body) routes 52 GPIOs and the full peripheral set — CAN, I²C, SPI, UART, and the integrated 8-channel 10-bit ADC — to a single board layer for most designs.
On-chip brown-out detect, POR, and watchdog timer reduce the external supervisor BOM — the MCU self-recovers from a supply glitch without a discrete reset IC.
The 100-LQFP package provides 52 GPIOs and an 8-channel 10-bit ADC.
